I'm needing to troubleshoot a IR problem I have on the right side of my S60 so I need to know the correct terminology to search. What do we call it when there are vertical band or bands brighter/higher contrast than rest of display?

Over voltage?

On a grey hex#666666 the bands appear as burn in, along with the HUD from a game I play, yet it's impossible the bands are burn in as I've never had such an image, they are smaller than the black area created from 4:3 material.

I should have had the bands taken care of when I was still under warranty.

On my VT60 it shows Native (not Normal, as per the recommended settings) as an option for the Color Gamut.

Is it native or rec 709?

Also, for picture modes, I only have one mode called Custom. So how do you apply the day and night pro mode recommended settings?
Do you just pick two of the picture modes and apply the settings to each?

I used the Day settings on Custom and the Night setting on Cinema. Is this how it's intended to be applied?

You need to unlock the pro picture modes. Menu, setup, professional mode set to on.

Curiously, I have found that if the HDMI Content Type is set to Photos, that doesn't happen. The lines remain black and white. I've tested this using my set top PVR, which I'm guessing does not do 4:4:4 output.

And in his review of the 42" ST60, David Mackenzie writes:

"If you’re using a PC with the TX-P42ST60B, you can get full 4:4:4 chroma by using the [1080p Pixel Direct] mode, which on its own will result in large edge halos. These can be defeated by setting the “HDMI Content Type” for that input to “Photo”, although this may have an impact on colour accuracy with some content (it appears to make no difference for RGB content from computers, but changes colour decoding with YCbCr video, like what is commonly output by set-top boxes and disc players)."

I know people like to stick with more conventional settings, but you might wish to give that HDMI Content Type setting a try. It's interesting. It has a curious effect on THX Cinema, too.
